Picture for a moment a 19 1/2" monitor (viewable diagonal) sitting on a pivot stand that if you are observant you will notice is slightly thicker than usual, with a keyboard and mouse sitting in front of it. Beautiful isn't it?

If you wander around to the back you will notice a power cable going to the monitor and a cable going from the monitor to the swivel base. The power supply is in the monitor and in the swivel base is the computer. On the back of the base there is the afore mentioned video and power connection; keyboard, mouse, and auxilary ports; and a removible network card. My network card has a RJ-45 connector (10-base-T ethernet), an AUI connector (DB15 with the funky slide latch), and link and polarity LEDs.

Your usual for Xterminals [[bootp]], [[tftp]] load of kernal image. havn't yet found a image with a valid checksum to test boot with. There are two eproms on the NIC that are in the first of three 16 bit banks. Decompiling is started, but this is my first mips project.

These pictures are taken from a diffrent model but are unmistakably similar to the network card in my box with the exception of the tranciver, connectors and labels on the rom chips. Note that there are two rom chips per bank, and three banks.

Wont't talk to my ethernet switch. add a hub, and it works fine. go fig.

===Update===

+

The network card that i have has an RJ45 connector and an aui connector. If a cable is plugged in to the RJ45 connector and directly into a switch, there are severe failures. from reading elseware this appears to be relaited to a link test conflicting with duplex negeoation. Another workaround is to use an external tranciever possably with a modified aui cable. I plugged a tranciever directly into the aui port (no cable used) and it will now talk to the switch without the aid of a hub. --[[User:Bhildred|Bhildred]] 02:44, 4 Aug 2005 (BST)
